[pass] There is no assurance this key belongs to the named user

[Roman Valls]

Hello list,

I'm having some issues with pass on one of my machines (works on the others):

$ pass generate social/quora.com 14 -c
gpg: 92EB4184: There is no assurance this key belongs to the named user
gpg: [stdin]: encryption failed: Unusable public key
Copied social/quora.com to clipboard. Will clear in 45 seconds.

$ cat cat .password-store/.gpg-id
08F80CB5

$ gpg --list-keys 08F80CB5

pub   1024D/08F80CB5 2001-11-29
uid                  Roman Valls <brainstorm at nopcode.org>
...
sub   1024g/92EB4184 2001-11-29

The show command works without a glitch, only the generate and insert
commands (adding new passwords) fail.

Any hints?

Thanks!
Roman
